When I tried on the prototype of this jacket at Trail Days in Damascus earlier this year, I knew I’d be getting one! I think my search for the perfect backpacking jacket is finally over! Bonus that it matches my Zpacks full zip sleeping bag! Zpacks does not disappoint. Just get one.

When those cold nights in the backcountry hit, stay warm and cozy with the Zpacks Down Jacket. Striking the perfect balance of warmth and weight, our ultralight down jacket is the go-to insulated layer for outdoor adventurers looking to beat the chill at an unbeatable weight!

Couldn’t be happier with this down hood. Perfect for quilt users, doesn’t slide around or off your head at night like a beanie can on straight, slick hair. Much better than the hood on a sleeping bag, which can slide into your face when you turn, and of course can’t be detached for use as a separate warm hood. The ultra light weight is remarkable. It’s very warm and has a cozy fit and feel.

Get ready for sweet dreams on cold nights when bundled up with the Zpacks Down Hood. A perfect companion to your ultralight down quilt, stay cozy and snug tucked away from the cold.

A down hood can move with your head as you turn side to side in your quilt, unlike an integrated mummy bag hood. You can also wear it around camp, or tuck it inside your camp pillow when you don't need it.

Zpacks Down Hoods are reversible, face whichever color you prefer outward.

Keep your hands warm when temperatures drop without weighing down your pack. The Zpacks Down Mittens deliver an excellent warmth-to-weight ratio for cold mornings, high-elevation camps, and nights around the campsite.

The fully reversible design lets you choose which color you prefer, while the soft, lightweight construction packs down small when not in use. Integrated snaps allow the mittens to clip together for storage, helping keep the pair organized inside your pack.

Whether you’re warming up after a long day on trail or adding extra protection on a frigid morning, the Zpacks Down Mittens are a simple, ultralight way to keep cold hands from slowing you down.

Treat these mittens like sleeping bags for your hands. They are great for around camp, sleeping, or even hiking, but it is not advised to wear them while using trekking poles due to abrasion.

Complete your down insulation system with our ultralight Down Jacket, Down Booties, and Down Hood.

I’m a cold sleeper and was looking for options to help keep my feet warm through out the night. In the past I’ve used wool socks which helped but didn’t quite keep the chill out. The first night I used the goose socks it was like heaven! They are so lightweight and add noticeable warmth! These will extend my hiking season well into the late fall, worth every penny!
